ld: Remove unused expression state 

Previous commit removed all uses of the defsym field within the linker
expression union.  This commit cleans up the now redundant state.

ld/ChangeLog:

	* ldexp.h (union etree_union): Remove defsym field.
	* ldexp.c (exp_assop): Remove defsym parameter, and use of defsym
	parameter.
	(exp_assign): Remove passing of defsym parameter.
	(exp_defsym): Likewise.
	(exp_provide): Likewise.
